The GoPro camera is a great tool for getting personal POV videos, but challenges arise when you want to mount the camera to, say, a car. Instructables user gjchandler offers a simple solution: use magnets.

To put this mount together, you'll need some washers, bolts, and a 25lb. disc magnet. You can also use the standard GoPro tripod mount for this project. All in all, the parts will cost you $9-11 depending on what you get, which is an incredibly cheap way to mount an HD camera on your car to get some very cool video. If you want to give it a shot, check out Instructables for the full how-to.
